The Gloucester County Sheriff’s Office received a donation of naloxene, which can reverse the effects of an overdose and cause immediate withdrawal symptoms, the agency announced this week.

The EVZIO naloxene auto-injectors were provided by kaléo, the Richmond, Virginia-based pharmaceutical company. According to a news release from the sheriff’s office, EVZIO is a “pre-filled, single-use, hand-held auto-injector that works by temporarily blocking the effect of an opioid, potentially reversing the life-threatening respiratory depression and allowing the recipient to breathe more regularly.”

It uses voice and visual cues to guide the user. Those injected still require medical attention after.

“We are pleased to be making this donation as a part of our commitment to widen access to naloxone,” T. Spencer Williamson, CEO of kaléo, said in the news release. “We are honored to support the outstanding efforts of the first responder community to help save the lives of those who are experiencing an opioid overdose.”

A Gloucester deputy used the drug on July 19, one day after receiving training, to save an unresponsive male who was believed to have overdosed, the news release said. The male later recovered at the hospital.

Four people die each day in Virginia from an overdose of heroin or opioid prescription painkillers. Last year, 1,133 deaths were reported in the state from heroin or opioids, which is more people dying from overdoses than in car crashes.
